Sig Sauer 1911x 45 ACP 5 inch 8+1 Nitron Finish

The SIG 1911XR45BXR3RXX 1911X blends classic 1911 ergonomics with modern duty and competition features, offering a 5" stainless-steel barrel in .45 ACP, an SAO flat-blade trigger, and a black Nitron steel frame with an undercut trigger guard and removable magwell for faster reloads and positive hand placement under recoil. The XSERIES slide is optic-ready with an optic cut and aggressive front/rear serrations and ships with XRAY3 Day/Night sights so shooters retain sight picture if the ROMEO-X is not in use; the factory-installed ROMEO-X red dot brings a 2 MOA dot with 32 MOA circle, low deck height for iron co-witness, MOTAC and D.A.R.C. technologies, side brightness control, and a threaded battery cap for tool-free battery changes—features that benefit action shooters, competitive carry users, and duty applications where quick target acquisition matters. Controls include extended slide release and ambidextrous thumb safety levers, custom black G10 LOK grip panels for traction, and a stylized slide and checkered front strap for handling. As part of SIG SAUER's 1911-XSERIES, this pistol targets those who want a traditional 1911 feel combined with optics-ready performance for range work, competition stages, and defensive roles.
